* [CIFS] clean up some hard to read ifdefsSteve French2008-02-12
| | | | | | | | Christoph had noticed too many ifdefs in the CIFS code making it hard to read. This patch removes about a quarter of them from the C files in cifs by improving a few key ifdefs in the .h files. Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] fix unicode string alignment in SPNEGO setupJeff Layton2007-12-30
| | | | | | | | | Unicode strings need to be word aligned, but the code that handles that is currently not taking the length of the SPNEGO blob into account. Fix it to do so. Signed-off-by: Jeff Layton <jlayton@tupile.poochiereds.net> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] use krb5 session key from first SMB session after a NegProtJeff Layton2007-12-30
| | | | | | | | | Currently, any new kerberos SMB session overwrites the server's session key. The session key should only be set by the first SMB session set up on the socket. Signed-off-by: Jeff Layton <jlayton@tupile.poochiereds.net> Signed-off-by: Steve French <sfrench@us.ibm.com>
* [CIFS] Have CIFS_SessSetup build correct SPNEGO SessionSetup requestSteve French2007-11-16
| | | | | | | | | | | | | | | Have CIFS_SessSetup call cifs_get_spnego_key when Kerberos is negotiated. Use the info in the key payload to build a session setup request packet. Also clean up how the request buffer in the function is freed on error. With appropriate user space helper (in samba/source/client). Kerberos support (secure session establishment can be done now via Kerberos, previously users would have to use NTLMv2 instead for more secure session setup).

* [CIFS] Fix buffer overflow if server sends corrupt response to smallSteve French2007-11-13
| | | | | | | | | | | | | | | | | | | request In SendReceive() function in transport.c - it memcpy's message payload into a buffer passed via out_buf param. The function assumes that all buffers are of size (CIFSMaxBufSize + MAX_CIFS_HDR_SIZE) , unfortunately it is also called with smaller (MAX_CIFS_SMALL_BUFFER_SIZE) buffers. There are eight callers (SMB worker functions) which are primarily affected by this change: TreeDisconnect, uLogoff, Close, findClose, SetFileSize, SetFileTimes, Lock and PosixLock CC: Dave Kleikamp <shaggy@austin.ibm.com> CC: Przemyslaw Wegrzyn <czajnik@czajsoft.pl> Acked-by: Jeff Layton <jlayton@redhat.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

* [CIFS] Fix oops when Windows server sent bad domain name null terminatorSteve French2007-01-21
| | | | | | | | | | | | | | Fixes RedHat bug 211672 Windows sends one byte (instead of two) of null to terminate final Unicode string (domain name) in session setup response in some cases - this caused cifs to misalign some informational strings (making it hard to convert from UCS16 to UTF8).

* [CIFS] Fix mount failure when domain not specifiedSteve French2006-11-08
| | | | | | | | | | | | | | | | Fixes Samba bugzilla #4176 When users do not specify their domain on mount, 2.6.18 started sending default domain instead of a null domain (which was the only way on some servers to use a default domain). Users of 2.6.18 who did not specify their domain name on mounts to certain common Windows servers that were members of a domain, but not the domain controller, would get mount failures which they did not get in 2.6.18 This fixes that issue and should remove complaints about mount behavior changing.

| * [CIFS] Do not send newer QFSInfo to legacy servers which can not support itSteve French2006-09-30
| | | | | | | | | | | | | | | | | | | | | | | | Fix dialect negotiation to save off when we have negotiated lanman. This allows us to avoid sending some somewhat newer requests that the server can not handle and go directly to the older version (infolevel) of the same call. Make sure we try to negotiate a level which allows us to get the server OS (which we check so we can detect Win9x vs. other legacy servers and eventually work around the Win9x DOS time bug (they reverse date/time fields).

* | [PATCH] namespaces: utsname: use init_utsname when appropriateSerge E. Hallyn2006-10-02
|/ | | | | | | | | | | | | | | | | | | | | In some places, particularly drivers and __init code, the init utsns is the appropriate one to use. This patch replaces those with a the init_utsname helper. Changes: Removed several uses of init_utsname(). Hope I picked all the right ones in net/ipv4/ipconfig.c. These are now changed to utsname() (the per-process namespace utsname) in the previous patch (2/7) [akpm@osdl.org: CIFS fix] Signed-off-by: Serge E.

* [CIFS] NTLMv2 support part 5Steve French2006-06-08
| | | | | | | | | | | | | | | NTLMv2 authentication (stronger authentication than default NTLM) which many servers support now works. There was a problem with the construction of the security blob in the older code. Currently requires /proc/fs/cifs/Experimental to be set to 2 and /proc/fs/cifs/SecurityFlags to be set to 0x4004 (to require using NTLMv2 instead of default of NTLM) Next we will check signing to make sure optional NTLMv2 packet signing also works.
